 I'm getting errors which crash mplayer's ao_pulse sometimes. Both seem to
 happen on stopping playback, making switching to next file in playlist
 impossible. They are

 mplayer: pulse/mainloop.c:287: mainloop_defer_enable: Assertion
 `e->mainloop->n_enabled_defer_events > 0' failed.

 It produces segfault and leaves core file, here is trace:

 And another one:
 mplayer: pulsecore/queue.c:67: pa_queue_free: Assertion `q->length == 0'
 failed.

 This one leaves no trace, just crashes, but reports that it happens in
 uninit function, which looks like this:
 {{{
 static void uninit(int immed) {
     if (stream && !immed) {
             pa_threaded_mainloop_lock(mainloop);
             waitop(pa_stream_drain(stream, success_cb, NULL));
     }

     if (mainloop)
         pa_threaded_mainloop_stop(mainloop);

     if (stream) {
         pa_stream_disconnect(stream);
         pa_stream_unref(stream);
         stream = NULL;
     }

     if (context) {
         pa_context_disconnect(context);
         pa_context_unref(context);
         context = NULL;
     }

     if (mainloop) {
         pa_threaded_mainloop_free(mainloop);
         mainloop = NULL;
     }
 }
 }}}
